PAINT 0R VARNISH REMOVER.

No Drawing.

To all whom it may concern i Be it known that I, CARLETON ELLIS, of

Montclair, Essex county, New Jersey, have made certain new and useful Inventions Relating to Paint ,or Varnish Removers, of

which the following is a specification.

This invention relates to paint or varnish removers and relates especially to removers containing solvent material of a generally ketonlc character, such as plnacolins and condensation products of the higher ketones and containing six carbon atoms which are specially desirable for the'solution or soften in of shellac or other varnish material.

the manufacture of acetone, calcium acetate is generally employed as a raw ma terial and the commercial processes produce a considerable proportion of oily body'as Well as the acetone desired. This oily material may be separated from the acetone by agitation with water which absorbs the acetone andsimila'r Water-soluble ketones, leaving the other materials in a separated condition. This residual oily material comprises pinacolins and condensation products of the higher ketones. This material may be de odorized, that is, deprived of its disagreeable odorto a considerable extent When used for removers by treatment with metallic sodium or similar material which seems to combine with these substances to form polymeric bodies which are solid at ordinary temperatures and which may be more readily separated from the liquid components distillation. Metallic sodium also seems to reduce certain unsaturated com-.

izing process and distillation of the treated material the ketonie condensation products comprislng plnacolin's and allied bodies may be used in preparing paint or varnish removers either alone or in conjunction with loosening finish solvent material, that is solvents having a generally alcoholic character or action in removers and comprising various alcoholic or ketonic bodies; and in con- Specification of Letters Patent.

junction with suitable penetrating finish solvent material, that is solvents havinga generally benzolic character or action in removers, such as benzol, its homologues or other wax solvents. Itis understood, of course, that stiffening materials, such as wax, wood flour, whiting, infusorial earth and the like may also be used to increase the consistency of the compound.

Other ketonic condensation products having six carbon atoms and allied to the pinacolins are suitable Ethyl propyl ketone C H COC H is obtained by the distillation of a mixture of propionate and butyrate of lime; its boiling point is 122-124 C. Methyl butyl ketone CH CO(CII CIrI is obtained when distilling calcium butyrate; its boiling point is 127. Methyl brom butyl ketone CH COCH CH CI-I CH Br is an illustrative halogenated derivative of the boiling point of 214 C. at 718 mm. Methylethylacetone CILCOCI-I- (CHQC H having the boiling point of 118. C., has a pep e'rmint like odor. Ethylisopropylketone, H,,GOCH (CH 2 has the boiling point of 114 C. Methylisobutyl ketone CH COCH CH CH ,having the boiling point of 115 at 745 mm., has a strongly camphoric odor. Methyl bromisobutyl ketone CI LCOCH CH(CHQCl'l Br is a viscous liquid, having the boiling point of 135140 C. at100 mm. 1-hydroxy-5-ketohexane (sometimes called acetylbutyl alcohol) CH COCH CILCH CH OH has the boiling point of 226 at 760 mm. Methyldehydr'ohexo'ne is an anhydrid of the preceding compound and has the boiling point of 109. Chlormethylacetobutyl-carbonol CH .CLCH(()IUCH CILCOCH has the boiling point of 115 C. at 20 mm. 4-hydroxy- Q-keto--methylpentane, also called diacetone alcohol CH .CO.CH C(CH,) OH has the boiling point of 163-5 C. 5-hydroxy-2-ketot-methylpentane also sometimes briefly spoken of as acetylisobutyl alcohol, CH COCH CH(CH )CH OH has the boiling point of 140 at 100 mm.. Mesityl oxid (isopropylidene acetone) 2-methyl-2-pentenone (CH C :OH.CO.CH having the boiling point of 130 C. smells like peppermint, Mesityl oxid dibromid (l H OBr is a Patented Nov. 24, 1914.
